ปรับขนาด PDF

Yes. ปรับขนาด PDF is completely free with no sign-up, no watermark and no daily limit. There is no paid tier — every tool on iAdorePDF is free to use as often as you like.

Yes. ปรับขนาด PDF runs entirely inside your browser, so your file is never uploaded to any server. Nothing leaves your device, which makes it safe for confidential documents.

No. ปรับขนาด PDF works in any modern browser — Chrome, Safari, Firefox or Edge. There is nothing to download and no account to create.

Yes. ปรับขนาด PDF is built mobile-first and works on iPhone and Android exactly as it does on a computer, straight from the browser.

Open the page, drop your file into the upload box (or tap Select file), choose your options, then press the start button. Your result downloads straight to your device.

There is no server limit because the work happens on your own device. The practical ceiling is your device memory; files up to about 100 MB are comfortable on most phones and much larger on a computer.
